CONTROLLING DEVICE FOR ELECTRICAL SYSTEMS.

Specification of Letters Patent.

Application filed February 21, 19 19. Serial No. 278,391.

To all whom it may concern Be it known that I, WILLIAM H. MOONEY, a citizen of the United States of America, residing at Dayton, county of Montgomery, State of Ohio, have invented certain new and and useful Improvements in Controlling Devices for Electrical Systems, of which the following is a full, clear, and exact descrip= tion.

This invention relates to electric systems for an internal-combustion or explosion engine, including a motor for starting the engine, devices for supplying ignition to the engine and a source of current such as a storage battery.

An object of the invention is to prevent waste of current of the battery. To accomplish this object I have provided manually controlled means for connecting the ignition devices and battery and other manually controlled means for connecting the battery with the starting motor, said motor controlling means being ineifective unless the ignition devices are connected with the battery by said first named means.

Other and further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of the present invention is clearly shown.

In the drawing is shown a wiring diagram which includes the features of the present invention. I

In the drawing an internal combustion onwhich may be connected with the engine for starting purposes in any suitable manner. The drawing shows a pinion 22 having a slidable driving connection with the motor shaft 23. Pinion 22 is moved bysuitable mechanism not shown, into engagement with the flywheel gear 24.

A storage battery or other source of cur rent which is grounded at 26 is connected by means of a wire 27 with a switch element 29 of a relay switch 28. A relay magnet winding 30 is adapted when energized to cause the attraction ofan armature 31 toward a core 32 and thereby effect the movement of the switch element 29 toward a coiiperating switch element 33. Switch element 33 is connected by wire 34 with tor 21 and the motor circuit is completed through a ground connection 35.

Current from the battery may be permitted to pass when desired, through an ammeter 40, wire 41 to a switch contact 42 mounted on a support 43 of insulating material. A movable switch contact 44 is mounted upon a shaft 45 but insulated therefrom, and said shaft 45 is adapted to be turned by the lever 46. This switch element 44 is yieldingly maintained in the off position as shown in the drawing by means of a spring 47 having a portion thereof engaging a detent 48 formed upon the element 44. When the lever 46 is turned counter clockwise until second detent 49 is engaged by the spring 47, a segmental portion 50 provided on the said element 44 will move into wire 41, contact 42, switch element 44, con-v tact 51, wire 54, switch terminal 55, wire 56 to the primary winding, not'shown, of ignition coil 57. The other end of the'primary wire of ignition coil 57 is connected by wire 58 with an ignition timer 59 having a ground connection 60, whereby, when the contacts of the timer are closed, the primary ignition circuit will be completed. The high tension rminal of the ignition coil 57 is connectedbylmeans of a wire 61 with an ignition distributer 62 which iscontrolled in conjunction with the timer 59 and has terminals each connected with a spark plug in each of the engine cylinders, so that the ignition system just described will furnish complete ignition for the engine. A second primary ignition circuit includes battery 25, ammeter 40, wire 41, switch contact 42, switch member 44, contact 53, wire 63, primary winding, not shown, of ignition coil 64, wire 65, ignition timer 66, also connected with the ground connection 60. The high tension winding of the ignition coil 64 is connected by wire 67 with the ignition distributer 68 which operates in conjunction with the timer 66 the starting mo-' Patented Dec. 27, 1921.

and has its terminals connected with spark plugs in each of the'engine cylinders. It will be seen that this second ignition system just described will also furnish complete ignition for the engine.

Condensers 69 and 70 are connected in shunt with timers 59 and 66, respectively, in order to reduce sparking at the timer contacts.

The ignition timer and distributer ele ments just described are preferably included in a single ignition unit, and said. elements are all 0 erated by common driving connection wlth the engine. Such an i nition unit is described and claimed in my atent No. 1,348,368, issued August 3, 1920, and further description thereof is considered unnecessary as the specific construction of this ignition unit does not form a part of the present invention.

The switch element 44 is provlded w1th a third detent 71 which, if the switch lever 46 is turned still farther in a counter clock- 4 gine will be supplied with ignition through the agency of one of the ignition systems. This arrangement may be found deslrable where it is desired to hold one of the other ignition systems in reserve in case of emergency and to economize the battery current.

The switch'terminal 55 is connected by wire 72 with a switch contact 73 which is adapted to be engaged by a movable contact 74 actuated by a button 75. Contact 74 is connected by wire 76 with the relay winding 30 having a ground connection 77. Whenever the switch element 44 connects one or both of the ignition systems with the I battery, by depressing button 75, current may be sent from the battery to' the relay winding .30. The relay energizing circuit includes battery 25, ammeter 40, wire 41, contact 42, switch element 44, contact 51, wire 54, terminal 55, wire 72, contacts 73 and 74,'wire 76, winding 30 and ground connections 77 and 26 to the battery 25.

It is apparent from the foregoing description that the present system prevents waste 61f battery current, due to an attempt to start the en'glne without the ignition system being connected to the battery. Before the relay winding 30 can be energized to effect theclosing of the motor circuit the ignia'ibn switch lever 46 must be turned to one "6fit'sonpositions and in which one or both 5f the ignition timers will be placed in condition for effective operation by the engine.

therefore it is useless'to depress the button 75 since no current can flow from the batter to the relay winding 30. w l

he lighting circuit for the automobile includes the battery 25, ammeter 40, wire 41, wire 80, overload circuit'interrupter 81, 4

Wire 82, switch contact 83, which is adapted to be connected with terminals 84, 85 and 86 by means of a switch element 87 mechanically connected to a lever 88 but insulated therefrom. Said member 87 is provided with detents 89, 90 and-91. In the off position as shown in the diagram, detent 89 is engaged by spring 47. When the lever 88 is turned in a clockwise direction until the detent 90 is engaged by the sprin 37 the switch contact will be connecte with terminals 84 and 85 thereby completing a lighting circuit through the rear light and side lights through ground connections to the battery. When the lever 88 is turned still farther in a clockwise direction until the detent 91 is engagedby the spring 47, the head lights will also be connected with the battery.

Suitable locking devices may be provided for locking the ignition switch lever 46 in the off position when the car is left standing, thereby assisting in preventing theft of the car and preventing depletion of the storage battery by meddlers.

While the. form of mechanism herein shown and described constitutes a preferred form of embodiment of the invention, it isto be understood that other forms might be adopted, all coming claims which follow.

I claim- 1. In a controlling device for electrical ignition and starting systems, *the combination with a contact connected with a current source; of a second contact connected with an ignition system; a starting motor s itch connected with said second contact; a" third contact connected with another ignition system; and a movable switch member having spaced wide and narrow contact segments whereby in the off position of said movable member none of the contacts will be connected, whereby" in one on positionof said'member all,three of said contacts will be connected, and whereby in another on position of said member only the first two contacts will be connected.

2. In a controlling device forveleotrical ignition and starting systems, the combina-' tion with a rotatable switch shaft; of a contact connected with a current source; a
